AbstractWater from 310 private wells and 158 stream sites in the Oak Ridges Moraine area of southern Ontario, an important aquifer complex, was sampled over three months during the summer of 1994. Chloride or nitrate in well- and stream-water samples, as components frequently associated with land use, are distributed in such a way as to suggest that shallow groundwater flow is responsible for most of the subsurface transport of these components. Very low sulphate concentrations occur in wells with intakes generally below the lowest elevation of Oak Ridges Moraine exposure. This result suggests groundwater flow also occurs on a larger scale approximately defined by the distance between the regional recharge area along the moraine crest and the low sulphate well area outside the Oak Ridges Moraine exposure.
